Answer:

you are correct

Step-by-step explanation:

The sequence has a common difference between consecutive terms

d = 9 - 5 = 5 - 1 = 1 - (- 3) = 4

This indicates the sequence is arithmetic with explicit formula

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 3 and d = 4, thus

a_{n} = - 3 + 4(n - 1) = - 3 + 4n - 4 = 4n - 7

Solve this question please?
Kitty [74]

Hence the value of the expression above are as listed below

<em>f(6+4) = 25</em>

<em>f(6)+f(4) = 20</em>

<em>f(6-4) = 1</em>

<em>f(6)-f(4) = 6</em>

<em>f(6*4) = 67</em>

<em>f(6)*f(4) = 91</em>

<h3>Functions and values</h3>

Given the expression below f(x) = 3x - 5

f(6+4) = f(10) =3(10) - 5

f(6+4) = 25

f(6) = 3(6) - 5

f(6) = 18 - 5 = 13

f(4) = 3(4) - 5

f(4) = 7

f(6)+f(4) = 13+7

f(6)+f(4) = 20

f(6-4) = f(2) =3(2) - 5

f(6-4) = 1

f(6) = 3(6) - 5

f(6) = 18 - 5 = 13

f(4) = 3(4) - 5

f(4) = 7

f(6)-f(4) = 13-7

f(6)-f(4) = 6

f(6*4) = f(24) =3(24) - 5

f(6*4) = 67

f(6) = 3(6) - 5

f(6) = 18 - 5 = 13

f(4) = 3(4) - 5

f(4) = 7

f(6)*f(4) = 13*7

f(6)*f(4) = 91
